An existing cluster has an application node and database node. Changes in the application  require both nodes to have access to the other’s data all of the time. 
Which facility managed by HACMP can be implemented with the least amount of impact？（）   

A. Shut down one node at a time and let the other node serve the application
B. Stop HACMP with the forced option and perform migration of the disks on one node，then restart HACMP
C. Stop both nodes and perform the migration all at once using standard AIX commands in parallel， then restart the cluster
D. Use C-SPOC to add the new disks to the cluster and migrate the information off the existing disks， then remove the old disks with C-SPOC

A. Hardware address takeover must be configured.
B. IPAT via IP aliasing is required for EtherChannel.
C. EtherChannel must be defined as a separate network.
D. HACMP does not support the fallover of EtherChannel.

A. IPAT using IP Replacement without MAC address takeover.
B. IPAT using IP Aliasing and hardware MAC address takeover.
C. None because continuous telnet connectivity cannot be provided with HACMP.
D. Shared service IP address assigned to multiple network interface cards on each node.
